Can Yeast Save Endangered Psychedelics?

As the psychedelic renaissance surges, wild sources are collapsing under demand—peyote takes decades to grow, safrole extraction is destroying Southeast Asian forests, and Sonoran Desert toads are being overharvested. In his book Bioengineering Enlightenment, Prof. Jeffrey Gerst proposes a radical solution: engineer yeast or fast-growing plants to produce psychedelic compounds sustainably. But at what cost? Dennis McKenna warns this could strip these substances from their cultural and ecological roots, veering into biopiracy. Together, they debate biotech vs. tradition, exploring alternatives like community-led agroforestry, symbiotic rights, and the “Om Fund” to return profits to Indigenous stewards. They also revisit Terence McKenna’s “Stoned Ape” hypothesis, asking whether paleogenomics could experimentally probe the evolution of human consciousness. - - - Jeffrey Gerst, born and raised in New York, is a Professor of Biology with over three decades of academic experience. He began his career at the Mount Sinai School of Medicine and has since held a long-standing position at the Weizmann Institute of Science in Israel, where he serves as the Besen-Brender Chair of Microbiology and Parasitology. His research focuses on how proteins are correctly localized within cells, particularly through the trafficking of messenger RNA (mRNA), a process essential for normal cellular function and disease prevention. Among his key contributions, Gerst’s work has demonstrated that mammalian cells can transfer mRNA between one another, revealing a novel form of intercellular communication. His lab is now exploring this mechanism as a potential gene therapy approach to treat rare genetic disorders such as Tay-Sachs, cystic fibrosis, and Gaucher’s disease by enabling targeted RNA delivery within the body. In addition to his biomedical research, Gerst advocates for the sustainable production of psychedelic compounds using genetic engineering. He is the author of Bioengineering Enlightenment and has presented this work at major scientific conferences. Learn more about your ad choices. Visit megaphone.fm/adchoices
